Bioshock: Infinite

So I've been tracking this game like a hound which means I might end up buying it soon, has anybody else played it? Has anybody else seen gameplay?

I think it looks sick and tackles some interesting themes even if it does get a bit racialist. I've seen like the first hour and a half of the game from youtube and it has some really tearing tense moments and the whole idea of a theocratic floating super American city seems like it could have a whole lot to it.

I've been watching an LP without commentary.
